This free, family-friendly annual event, named after the consummate Renaissance man, celebrates art and science in a one-day extravaganza on January 7 that is open to the public. Stillwater Area High School will be jammed full of educational science and art exhibits by Twin Cities area organizations, music, a competitive science event and special art and science demonstrations. But the heart of Da Vinci Fest will always be the student projects that make up the Art Fair, Science Fair and Film Fest. It’s not too early to sign up. The deadline for submissions is Dec. 15.
